The watershed of the rivers San Francisco and Parahyba, comprising part of the provinces of Piauhy, Maranham is the area of—1. The Acroas; 2. the Masacaras; 3. the Jaicos; 4. the Pimenteiras (Pimento Indians, the native name being unknown); 5. the Garanhuns; 6. the Ceococes; 7. the Romaris; 8. the Acconans; 9. the Carapotos; 10. the Pannaty.
The whole ethnography here is most obscure. The Acroa, probably represent a large class. In Martius's paper they fall into two divisions, the Acroa-assu (Great), and the Acroa-ming (Little) Acroa. Besides this, however, separate mention is made of the Acrayás, with the remark that they are probably the same as the Acroa. If so, three fresh tribes become Acroa; viz., the Aracujás, the Pontás, and the Goghés—these being specially stated to be Acrayá.
Again, in the "Atlas Ethnologique" we have a Ge or Geic vocabulary. It is marked, however, with a note of interrogation(?), which casts a shade over the light it would otherwise give. As it is, however, it has considerable affinity to the Timbiras, a fact which, perhaps, identifies it with the Gés, though it complicates the ethnology still more.
The table-land which contains the head-waters of the river Tabajos, amid the primeval forests of the Mata Grosso, is the Campos dos Parecis, or the Plain of the Parecis. This is a convenient centre for the complicated ethnology of the area next in question, an area bounded (there or thereabouts) by the rivers Amazons, Madera, and Xingu, with the Tapajos in the middle of it.
Southward and Westward.—Here the Brazilian populations come in contact with those of Paraguay, the Chaco, and the Mission of Chiquitos; so that probably the ethnology is, partially at least, the same as for those areas.
